Email Marketing Software Cost: What 9 Platforms Charge in 2026

Short answer: email marketing software costs roughly $9 to $39 a month at 1,000 contacts in August 2026. Brevo starts at $9, MailerLite and Constant Contact at $12, Mailchimp at about $20, Klaviyo at about $30, and Kit at $39. Those entry numbers tell you very little on their own, because each vendor bills on a different unit. The same list can produce quotes that differ by 5x depending on whether the platform counts contacts, emails sent, active profiles, or subscribers.

Below is what nine platforms actually charge, checked against vendor pricing pages in August 2026, plus the repricing that has made most of the comparison articles currently ranking for this query wrong.

How much does email marketing software cost?

Here is the entry tier for each of the nine platforms most US small businesses shortlist, priced at roughly 1,000 contacts.

Two things stand out. Kit has the most generous free tier in the category by a wide margin and the most expensive entry paid plan, which is deliberate: it wants creators to grow free and pay for automation later. And Brevo is the only major platform that does not charge you for storing contacts, which changes the calculation completely for large, rarely mailed lists.

Why does email marketing software get more expensive as your list grows?

Because almost every vendor in the category ties price to list size rather than to usage or value. It is a pricing model, not a cost model. Storing an extra 5,000 email addresses costs the vendor a rounding error; charging for them is simply how the category decided to capture more revenue as customers succeed.

The practical consequence is that your bill grows fastest exactly when marketing is working. Here is how the ladder looks on the platforms with verified public tiers.

A business going from 1,000 to 10,000 contacts on Omnisend sees its bill go up more than 5x for software that does not do anything new. That is worth building into your plan before you start running list-growth campaigns.

The exception is Brevo. Because it bills on emails sent, a nonprofit sitting on 40,000 contacts it mails quarterly pays far less there than anywhere else on this list, while a 2,000-contact store that emails four times a week pays more. Neither model is better in the abstract. They are better for different send patterns, and the only way to know which you are is to write down your contact count and your monthly send volume before you shop.

What changed in the last twelve months

This category has been unusually unstable, which is why a lot of the pricing content ranking today is quietly out of date. Four material changes since mid 2025:

If a comparison article still quotes a $38 flat Flodesk plan, a $9 MailerLite Growing Business tier, or tells you Omnisend Pro includes SMS credits, it has not been checked since last year. Flodesk in particular was recommended for years specifically because of the flat plan, and a lot of that advice is still circulating after the plan stopped existing.

The lesson is simple: price your shortlist against the vendor's own pricing page on the day you buy, not against a roundup.

What is the cheapest email marketing software?

On sticker price, Brevo at $9 a month and MailerLite and Constant Contact at $12. If your list is genuinely small, Mailchimp's Essentials at $13 for 500 contacts is competitive too.

But cheapest per month and cheapest per outcome are different questions. Three costs regularly get left out of the comparison:

Branding removal. Several platforms put their own logo in the footer of your emails on lower tiers and charge to take it off. Brevo treats it as a paid add-on.

Features gated a tier up. Constant Contact's Lite plan does not include the automation and segmentation most buyers assume they are getting; that starts at Standard, at $35 (the full Constant Contact pricing ladder shows how steeply that gap widens as the list grows). ActiveCampaign sells CRM pipelines, SMS, and custom reporting as add-ons on top of the plan price. Check that the tier you priced actually contains the feature you shortlisted the tool for.

Overage and growth. A plan that fits today at 1,000 contacts is the plan you will be paying triple for in eighteen months if list growth is part of your strategy.

Is free email marketing software enough?

For a first list and low volume, yes. Kit's free plan covers 10,000 subscribers, which is more than most businesses will have for years. Brevo's free tier allows 300 emails a day against unlimited stored contacts. Mailchimp and Omnisend both free up to 250.

Free stops working at a predictable point: when you need real automation depth, when you want your own branding in the footer, or when your send volume crosses the daily cap. Because that transition is where the actual spending starts, choose your platform on what its paid tier costs at the list size you expect in a year, not on how generous the free plan looks today.

How much should a small business budget for email marketing?

For software alone, $15 to $50 a month covers most US small businesses under 5,000 contacts. Ecommerce stores that want revenue attribution and product-data flows should budget $30 to $150. That is a small enough line item that software cost is rarely the thing worth optimizing.

The budget question that actually matters is the next one.

Does email marketing software cost more than the person writing the emails?

No, and it is not close. This is the number the comparison tables never show.

Every platform on this page automates delivery. Not one of them writes the email. You still choose the angle, write the subject line, draft the body, pick the offer, and repeat next week. If you do that yourself, the real cost of email marketing is a few hours of your time per send, every send, forever. If you hire a freelancer to write them, even at the low end of typical freelance copywriting rates, a single monthly campaign costs more than any of the software above, and a proper sequence costs several times that.

That imbalance is why so many small businesses pay for perfectly capable email marketing software and still send four times a year. The $12 was never the obstacle. The blank draft on a Tuesday was.

It is also why flat-priced platforms that draft the content behave differently on a spreadsheet. AutoMarketer includes email campaigns and sequences on the Growth plan at $149 a month, or $119 billed yearly, and the price does not move as your list grows. Against a $12 sender that number looks expensive until you put the writing back into the comparison, at which point it is competing with a freelancer rather than with a send button.

How to actually choose

Four questions, in this order:

1. What is my contact count and my monthly send volume? Write both down. This single step eliminates half the shortlist, because it tells you whether a contact-billed or send-billed model is cheaper for you.
2. Do I sell online? If yes, Klaviyo or Omnisend will likely pay for themselves through revenue attribution and product-data flows, and Klaviyo pricing is worth modelling against your actual profile count first. If no, you are paying for machinery you will not use.
3. Am I a business or a publisher? Creator tools like Kit and Flodesk are built for people publishing to an audience, not for businesses running segmented campaigns.
4. Is the writing handled? If yes, buy the cheapest sender that has your features. If no, cheap sending software will not solve your problem, and you should be comparing email marketing platforms that draft the campaigns against the cost of hiring instead.

Most buyers work through the first three questions carefully and skip the fourth, then wonder why the tool they researched for a week sits unused. Answer it first.
